To in itmay concern: to receive the dependingannular boss 6 of Be it known that we, EDWARD A. BAKER I andSAMUEL-W. Jonnsron citizens of the United States (sf-America, residing at Mansfield,'.in the county of Richland. and State of Ohio, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

This invention relates tocertain new and a collar bearing 7 which latter 'is also formed with 'a bore coincident with the bore of cap 4 and supports a bevel gear 8.

Suitable anti-friction bearings 7 are inter:

'posed'between the collarand cap. The gear 8 1s fixed to the upper-end ofa tubular rod .9rby a screw 10, or other fasteningmeans, 'sald screw doubly securing'the gear against j be subject to auninimum wear.

10 usefulimprovement s-in pumps and more particularly to that type of pumps in which is employed a rotary element for raising liquids, and it has for its primary aim to provide a novel, simple and cheaply constructed machine which wi11efl icient1y raise shaft 13 of a drive bevel gear -14: which water-in a steadyand continuous flow.

Threaded 011 the lower end of the pump casing is .9 by entering an aperture,provided in the latter. A bracket 11, detachably secured to the upper end portion-of the pump casmg, is provided with a bearing 12' for the relative rotary movement on the pump rod pump for manual operation, a; crank These, among other objects herein set ahead 16' of the pump cylinder 17, the latforth, are attained'by the constructipnillus-' ter being threaded into head 16 and-head I trated-in theaccolnpanying drawings, mi- .18 whereby the interior is accessible.

The ratio By having the shaft hollow, the air is displaced within the former as the water is elevated whicha'ctsmore or less as abalance or pressure equalizer, the bore of the shaft registering with the Opening for communicating below the cylinder.

What is claimed is:

I 1. In combination'with a pump cylinder and a shaft having a spiral blade thereon, said cylinder having an exteriorly threaded lower end, a head threaded over said cylin- 1 der lower end and having a spider abutting vthe bottom end of the cylinder, an internally threaded boss connected to the spider "and extending above the spider-and having its bottom extending flush with the bottom of sa ldhead, acollar bearing threaded into said boss and having a bore in which the lower end of said shaft rotates, balls on the "collar, and a collar on the shaft seating on said halls, said boss and collar bearing having central registering openings and said shaft having its lower end terminating between the endstof the first collar, and being hollow and registering with the openings 1n the boss and collar.

2; In combination with a-pump casing, a

head secured to therlower end thereof, a

pump cylinder connected td the head, a

head connected to. the lowerrend of the cyl inder and formed -with,a spider having a central bearing, a central bearing; borne by the first head, a hollow the casing and jo'urna d in said bearings,

d extending into and a spiral blade carried by the/rod to fit the cylinder,-said blade extending from a point closely adjacent the upper bearing to a point closely adjacent the lower bearing, the reduced casing being secured to the upper bearing to 'receive water from the cylinder, and saidspider providing a' substantially annular inlet into the lower end of the cylinder, said blade being continuous .whereby the water that passes through the cylinder is constantly acted upon and uninterruptedly raised in-its passage throughout the length of the cylinder, the central bearing for thelower end of the rod being so arranged as to permit free and unobstructed inflow ofwater into the inner periphery of the hollow rod.

' 3. In combination with a pump casing, a

head secured to the lower end thereof, a

,jacent the lower bearing, a collar formed on pump cylinder connected to the head, a head connected to thelower end of the cylinder and formed with a spider having a centralbearing, a, central bearing borne by the first head, a hollow rod extending into theecasing and journaled in said bearing, a spiral blade fitted to the inner periphery of the cylinder and carried by the hollow rod; said blade extending from a point adjacent to the upper bearing to a pointclosely adthe upper head, said. casing being smaller in diameter than the cylinder, and attached to the collarof the upper headthereby suspending and supporting the cylinder; said spider providing a substantially annular inletinto the lower end of the cylinder and said blade being continuous whereby the water. that passes through the cylinder is constantly acted upon and uninterruptedly raised in its passage throughout the length of the cylinder in juxtaposition with the upper head and vforced through apertures in the head which are restricted to the size or smaller than the inner periphery of the small casing. g

4. In combination witha pump casing, a head secured to the lower end thereof, a pump cylinder connected to the head, a head connected 'to the lower end of the cylinder and formed with a spider having a central bearing, a central bearing borne by the first head, a hollow' 'rod extending-into the cas-' ing and journaled in said bearing to continually maintain the inner periphery thereof free from obstruction and open to admit "the inflow of water to assist in supporting the pump mechanism, a spiral blade fitted to the inner periphery of the cylinder and carried by the hollow rod; said blade .ex-

tending from a point adjacent to the upper 10s bearing to a point clo selyvadjacent the lower bearing, acollar formed on the upper head,

said casing being smaller in diameter thanF- the cylinder, and attached to the collarof the upper head thereby suspending and'supporting thecylindernsaid spider providing a substantially annular inlet into the lower end of the cylinder and said blade being continuous whereby the water that passes through the cylinder is constantly acted .upon and uninterruptedly raised in its passage throughout thelength of the cylinder in juxtaposition withthe upper head and forced through aperturesin the head which are restricted to the size or smaller than the mner periphery of the small casing.
